(WASHINGTON) -- House Majority Leader Eric Cantor knew of David Petraeus' affair with biographer Paula Broadwell almost two weeks before the former CIA director resigned his post. A senior Cantor aide told ABC News that the Republican congressman from Virginia learned about the FBI investigation that brought the affair to light in a phone conversation with an FBI agent Oct. 27.
Cantor then asked his chief-of-staff to pass the information along to the head of the FBI, Robert Mueller. Cantor spoke to no one else about the investigation, the aide said.
Hurricane Sandy delayed the message to Mueller until Oct. 31.
Petraeus admitted the extramarital relationship and submitted his resignation nine days later.
